Hi,

In writing several Makefiles, I come across a recurring problem. I don't have (and
don't want) "/cygdrive/c/Program Files/mspgcc/bin" in my path (using Cygwin
here, in case that's not obvious). However, msp430-gcc tries to exec msp430-ld and can't
find it.
To avoid adding the directory to the PATH you can do separate
compiling/linking:
CC := /cygdrive/c/Program\ Files/mspgcc/bin/msp430-gcc
LINK := /cygdrive/c/Program\ Files/mspgcc/bin/msp430-ld
...
module.elf : module.o
$(LINK) -o $@ $(LD_FLAGS) $* $(LIBS)
module.o : module.c module.h
$(CC) -c -o $@ $(CC_FLAGS) $<
The solution I'm looking for is to export PATH in a Makefile. I've tried a
couple variants. PATH=$(TOOLPATH):$(PATH) then 'export PATH'. For some
reason, make can't find msp430-gcc (I played around with a similiar problem a
few months ago, and localized it to a Cygwin problem either not exporting or
not inheriting variables correctly) I've tried 'export
PATH=$(TOOLPATH):$(PATH)', but make generates a circular reference error.
To avoid circular references try := instead of simple = (export PATH :=
$(TOOLPATH):$(PATH) ). Also make sure that the mspgcc toolchain and make
(!) is configured and built for cygwin and that very installation
location (/cygdrive/c/Prog....). However the compiler driver won't find
the linker as long as its location is not part of the PATH variable.

I'm not sure of the implications of this, but it seems that since msp430-gcc
execs msp430-ld, it should attempt to exec it normally, then if it fails, try
execing it with any explicit path information that msp430-gcc was invoked with.
